Ingredients

Scale
  • 1 lb ground beef (preferably lean for healthier options)
  • 2 large onions, thinly sliced
  • 3 cloves garlic, minced
  • 1/4 cup beef broth or red wine
  • 2 tbsp Worcestershire sauce
  • Salt and freshly ground black pepper to taste
  • 4 hamburger buns or sandwich rolls
  • 1 cup shredded melted cheese (Swiss, Gruyère, or cheddar)
  • Optional: toasted sesame seeds or chopped parsley for garnish

Instructions

  1. Caramelize onions: In a large skillet, melt butter over medium heat. Add sliced onions and cook slowly, stirring occasionally, until golden brown and caramelized (~15-20 minutes).
  2. Cook ground beef: Add ground beef to skillet, cook until browned, breaking apart with spatula. Drain excess fat if needed. Add minced garlic, salt, and pepper, cooking for an additional minute.
  3. Add liquids and simmer: Pour in beef broth or red wine along with Worcestershire sauce. Stir and simmer for 5-10 minutes to meld flavors.
  4. Assemble sandwiches: Spoon beef and onion mixture onto toasted buns. Top with shredded cheese and place under broiler or in a hot oven until melted and bubbly.

Notes

  • Use lean ground beef for a healthier version.
  • For sweeter onions, cook longer until deeply caramelized.
  • Can be prepared ahead and stored in the fridge for up to 3 days.
  • Freeze leftover beef mixture for later use.
